Correcting lag in the S4

I am a new convert to Android and am learning a lot from the forums. I read quite a bit from the forums and other reviews online that there is lag on the S4. I experienced some lag in the beginning, but now that I am using the Nova launcher all seems to be running smoothly. I hear people bash Touchwiz all the time and I really don't understand what the big deal is with that. Doesn't changing the launcher and using Titanium Backup to freeze and remove bloatware correct all the lag issues?

I was considering trying different ROM's but so far have not seen that the risk is worth the reward since I still have a lot to learn. I have had iPhones since the first one and have always jailbroke my iPhone, but now with Android you can do so much out of the box without trying new ROM's. It is so great to not worry about losing my jailbreak.

Not just that, people seem to bring up the lag forgetting that there has been many updates that rolled out to fix it. Especially verizon GS4s that got massive 1.8gb update that fixed everything, I asked verizon GS4s owners.

Any stutter that I had is now gone with an update last week. I even went back to the default 1x speed for those 3 dev options. And all is good, Twitter was the worst offender for me and it's smooth by default now.
